[LTP] [PATCH 0/1] fs_bind: Convert to ltp tests

[Joerg Vehlow <lkml@jv-coder.de>]

Hi everyone,

I know this is a huge changeset, but there is not really a good way to         
break it down into multiple commits. Every step in between would either
lead to a broken test suite or a change, that is then changed again.
So I made this one huge commit, that converts all of the tests of the     
testsuite in one go.

I added some minor bugfixes especially added umounts, because some where
missing and some were redundant. I also dropped all useless output (bare ls).

I may have overused EXPECT_PASS a bit here, but I think it does not do any harm,
if all mounts are checked.

Joerg
